SPRING-HUB FOB VEHICLE-WHEELS.

Specification of Letters Patent.

Patented Jan. 28, 191s.4

Application filed January 29, 1912. Serial No. 674,142.

To alten/10m t mng/ concern Beit known that I, .Io1r\v C. PEAnsoN, acitizen of the United States of America, residing at Natchitoches, intheA parish of Natchitoches and State of Louisiana, have inventedcertain new and useful Improvements in SpringsHubs for Vehicle-VVheels,o1' which the following is a specification.

This invention relates to spring hubs for vehicle wheels, the'object oftheV invention being to provide an improved device of this characteradapted to cushion the running gear `of the vehicle with relation to thebody thereof, while at the same time presenting a nonpuncturable surfaceto the road bed. This permits the elimination of the pneumatic tire withits many objectionable features.

. It is a further object of the invention to provide means for taking upwear between the moving portions of the hub and for preventing theentrance of dust, dirt and mud to the interior or spring containingportion of the hub.

Further objects and advantages of the invention will be set forth i'nthe detailed description which now follows. In the accompanying drawingFigure 1 is i a vertical sectional view of a hub constructed 30 inaccordance with the invention. Fig. 2 is a view .partly in section andpartly in side elevation, with certain of the disks removed, and Fig. 3is a side elevation of 'a complete wheel in which this hub .isembodied.

Like numerals designate corresponding parts in all of the figures of thedrawing.

Referring to the drawing, the numeral 5 designates an axle receivingrsleeve, which is externally threaded at each end at 6 for the receptionof nuts-7 and 8. :Fhesenuts have concave inner end faces 9 and 10,adapted to bear against concave-convex disks 11 and 12. These disks,which will be hereinafter referred to as dished disks, have their outeredges. bearing against circular plates 13 and 1l. These plate's 13 and14 have openings 15 formed therein to permit of a certain amount ofvertical play between the sleeve 5 and said plates. Extendingbetween thesleeve 5 and a rim 16, are substantially S shaped spring spokes 17.lVhile these spokes have been shown of S shape, it is ap arent that theymay be of other shapes an `serve the same purpose, as

long as they are spring spokes land extend between sleeve 5 and rim 16.The inner ends of these spokes are secured by screws or other fasteningdevices 18, to the sleeve 5, and by fastening devices 19 to the rim 16.The rim .is encircled by a spoke receiving ring 20. The rim 16 carriesdriving lugs 21, which project transversely from its sides, and arecounter-sunk into plates 13 and 14, as 1s best illustrated at the upperportion of Fig. l. Rigid Vspokes 22 extend radially from ring 20 andcarry an outer rim or felly 23, which may, ifdesired, be provided with asolid rubber tire 24 though the latter 1s not essential.

It isapparent that in operation, the spring spokes 1| cushion the axlewith relationv to folly 23. The openings 15 in plates 13 and 14 permitthe necessary vertical movement to .achieve this end. At this time, theouter edges of the dished disks 11 and 12 travel over the outer faces ofplates 13 and 1.4.. fl'hese dished disks provide means for taking up allwear between the parts, and they also provide means for resisting thegreat lateral thrust, which is brought upon wheels ot' -this characterwhen the vehicles upon which they are mounted tend to skid in turningcurves at high rates of speed. Furthermore, these. (lished diskscompletely cover the opening 15 and effectively prevent theI entrance ofdust, dirt and mud to the spring chamber formed between' said disks.

WVhile the elements shown and described are well adapted to serve thepurposes for which they are intended, it. is to be understood that theinvention is not limited to the precise construction set forth, butincludes within its purview such changes as may be made withln the scopeof the appended claim.

Having claim is In a device of the character described, the combinationwith a' horizontally disposed axle receiving sleeve, having its oppositeends external-ly threaded, of compression nuts threaded upon saidsleeve, saidcompression nuts having concave faces, a pair of opposeddished isks fitting upon said sleeve and against which the conoavedinner end faces of said nuts bear, a pair of plates having openingsformed therethrough for the assage of said sleeve, sald openings being ogreater diameter than describedV my invention, what I inner end ablelvertically, but transversely rigid exi said sleeve, the periple'ries ofseid dished plates bearing and pressing directly against disks bearingagainst said plates, a rim4 the edges yof said spokes. 10 morlntedbetween said plates at the outer n testimony whereof I aiiiX mysignature portions thereof, and spring spokes yieldin presence of twowitnesses.

\ JOHN C. PEARSON. tending between seid rim and the sleeve, and beingsecured to seid rim and sleeve et their opposite ends, the inner facesof said Wiinesses:` LENN G. HENRY,
